Hi Tom,
I understood your suggestion but it was necessary for me to generate such
content with the provided specifications.As suggested by Tom earlier i
tried the same transcodes ,but didn't achieve the goal to be able to play
it on some other player such as mplayer. An interesting observation is the
fact that when explicitly given the option of " mplayer -lavfdopts
format=flv -demuxer lavf temp.mpg" then no playback is observed with error
msg as:
#mplayer -lavfdopts format=flv -demuxer lavf
